• balise parameters : (obligatoire et unique) Balise englobante.
  • balise parameter : (nombre quelconque d'occurrence) Un paramètre du générateur.
    • attribut name : Nom du paramètre.
    • attribut min : Valeur minimal du paramètre.
    • attribut max : Valeur maximal du paramètre.
    • attribut step : Pas entre deux valeurs de paramètres (par exemple +1 ou *2).
    • attribut default : Valeur par défaut de ce paramètre.
